The End of End-to-End?

One of the major principles of the architecture of the Internet was encapsulated in a paper by Saltzer, Reed and Clark, "End-to-End Arguments in System Design". This paper, originally published in 1981, encapsulated very clearly the looming tension between the network and the application: "The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible." At the time this end-to-end argument was akin to networking heresy! more

FCC’s Stanford Hearing on Broadband Practices

About 300 people attended to the net neutrality hearing Thursday hearing which began with testimony from Larry Lessig, a Stanford Law School professor and founder of the Center for Internet and Society... The meeting was called by the FCC in reaction to the news that US net firm Comcast had been exposed as managing traffic by stopping some of its 13m customers uploading files to BitTorrent and other peer-to-peer networks. The FCC has started a formal investigation to see if Comcast merits a fine for its actions. more

Does Bell Really Have a P2P Bandwidth Problem?

Bell filed its response to the Canadian Association Of Internet Providers (CAIP) submission to the Canadian Radio-television and Telecommunications Commission (CRTC) on its throttling practices yesterday, unsurprisingly arguing that its actions are justified and that there is no need to deal with the issue on an emergency basis. Several points stand out from the submission including its non-response to the privacy concerns with deep-packet inspection... and its inference that P2P usage could be deemed using a connection as a "server" and therefore outside the boundaries of "fair and proportionate use" under typical ISP terms of use. more

Locking Out Competing Providers is Bad

Today one of the headlines in Computer Sweden was that there is a dispute between Telia and the regulator PTS in Sweden. PTS requires Telia to stop locking out competing TV-distribution companies for IP-TV in the access network (DSL) that Telia runs. Specifically, they lean towards the fact Telia is dominant provider of the copper, and require Telia to competitors give access to the larger frequency band in the copper that they claim is needed for TV distribution. more

Models for Muni WiFi Completely Neglect Technology Evolution

Modern travel means interminable waits, but it's a good time for reading. I finally read Wireless Pittsburgh: Sustainability of Possible Models for a Wireless Metropolitan-Area Network by Jon M. Peha, published in February as a working paper of the New America Foundation. The good news: it's full of interesting cost estimates and projected subscriber take rates based on specific demographics in Pittsburgh, Minneapolis and Philadelphia... The flaws in this study...

CAIDA and ARIN Release IPv6 Survey

The Cooperative Association for Internet Data Analysis (CAIDA) and the American Registry for Internet Numbers (ARIN) presented the results [PDF] of a recent IPv6 survey at the ARIN XXI Public Policy Meeting in Denver on April 7th. The survey involved over 200 respondents from a blend of Government, commercial organizations (including ISPs and end users), educational institutions, associations, and other profit and non-profit entities. The purpose of the survey, conducted between March 10th and 24th, was to capture IPv6 penetration data in the ARIN region... more

Retrograde Inversion of Telecommunications Policy

Going backwards upside down. That's what we're doing with telecommunications policy in the U.S. The Comcast affair should prompt a re-examination of many decisions the FCC, Congress, and the courts have made over the last few years. When the FCC reports on its reactions to Comcast's activities, the right response will be "You're asking the wrong question." "What is reasonable network management" isn't the question we should be asking... more

Comcast 1, E360 0

The judge in E360 vs. Comcast filed his order yesterday (read previous postings here and here), and to put it mildly, he agreed with Comcast. It starts: "Plaintiff e360Insight, LLC is a marketer. It refers to itself as an Internet marketing company. Some, perhaps even a majority of people in this country, would call it a spammer." ...and from E360's viewpoint, goes downhill from there. more

Overloading the Internet? Recent Media Reports Based on Dangerous Misinformation

The London Times article (and a similar one in the Guardian) are based on dangerous misinformation. The net isn't slowing down, and nearly no technical experts believe major "overload" problems likely on the backhaul, core, or decent local loop... Net traffic per user, as documented by Odlyzko and Cisco, has been growing at about 35-40% the last five years, and that growth rate is flat and possibly down the last two years. The net has been able to handle the increase without price increases, much less overload, because the primary and rate limiting equipment (switches, routers, WDM, etc.) have simultaneously been going down at a similar 35-40%. Moore's Law is bringing costs down and capacity up at a remarkable rate. more

NY Times Grossly Misreads WEF Report

Today's New York Times includes an article by John Markoff entitled "Study Gives High Marks to US Internet." But either John Markoff is fuzzy about exactly what the Internet is or he didn't actually read the report. His title is way off base. He did interview a few people who are quoted in the latter part of the article, so there is some information in the article. But he's done a major disservice for the many who read only the title or perhaps first paragraph... more

Whose Network Is It?

A reader sent me a link last week to a piece that doesn't speak highly of net neutrality. Clyde Wayne Crews wrote an article called "Dumb Pipes, a Dumb Idea: Net Neutrality as 21st Century Socialism" that calls for legislators to reject "nut" neutrality. "Elevating the principle of mandatory net neutrality above the principle of investor ownership and wealth creation in pipes and spectrum deflects market forces away from the infrastructure development that we need..." Did anyone else see a touch of irony in a letter to the editor... more

Cisco Speaks at FOSE on IPv6 Enterprise Architecture Transition

"The world is flattening," says Dave Rubal at the FOSE Conference and Exhibition this week in Washington, DC. "The race for IT dominance is on, and it is coming west." Mr. Rubal, Cisco's Worldwide Internet Protocol version 6 (IPv6) Task Force Lead, spoke of the tremendous race in IT dominance that is occurring, stating that the "mainstay technologies at the Beijing Olympics will be IPv6-powered." IPv6 is in line to replace version 4, but Rubal hinted that China and other Far East countries may be adopting the new version faster than the United States... more

New Publication on Updating the Anti-Cybersquatting Regime and Ad-Based Cybersquatting

Sealing the cracks: a proposal to update the anti-cybersquatting regime to combat advertising-based cybersquatting is the title of an article by Christopher Varas in the April issue of the Journal of Intellectual Property Law & Practice. In this article, the author labels "modern cybersquatting" the monetization of domain names through PPC advertisements, and says that brand owners lack effective tools to combat this practice... more

Who Makes the Any Apps Any Handset Call?

The Wall Street Journal today reported that FCC Chairman Kevin Martin wants to reject a Petition for Declaratory Ruling filed by Skype that would establish a wireless Carterfone policy, i.e., that wireless carriers must allow subscribers to use any compatible handset to access any application, content or software. Chairman Martin has confidence that the marketplace solutions obviate any necessary FCC intervention. Such optimism must derive in part from the apparently newfound willingness of one major wireless carrier, Verizon, to support aspects of open access. Perhaps Chairman Martin has confidence in the marketplace based on the magnanimous offer of most wireless carriers to pro-rate their early termination penalties by $5 a month. But here's the rub... more

Hot Architectural Issues for the Internet

The Internet Architecture Board's (IAB) chair, Olaf Kolkman, asked the members of the IAB to provide a statement paper each on what they believe the current most pressing issues in terms of Internet architecture are... I have thought about this for the past few days, and realised that it's hard to come up with overarching issues and even harder to come up with issues, where the IAB actually could make a difference. But I came with up with two issues. more
